Abstract
우리나라 연안 조위자료의 결측양상을 분석 제시하였다. 결측구간은 결측정보지시행렬을 이용하여 전체적인 결측양상을 파악할 수 있도록 도시하였으며, 시간적 공간적인 결측비율도 분석하여 제시하였다. 전반적으로 조위의 결측비율은 낮은 수준이나, 결측이 특정 조위관측소에 집중되는 경향을 보이고 있다. 또한 연속적인 결측자료 발생간격에 대한 자기상관함수를 분석한 결과, 조위자료의 결측은 무작위적으로 발생하고 있는 것으로는 파악되었다. The missing data patterns of tidal elevation data in Korean coasts are analysed and provided. The missing interval of the data is displayed for all stations using the missing data indicator matrix in order to identify the overall missing pattern. The spatial and temporal missing rates are also estimated. The total missing rate of tidal elevation data is low. However, most of the missing is mainly derived from just 1 or 2 specific stations. The autocorrelation function of the consecutive missing interval data also shows that the missing interval occurs randomly.
